Common Door and Window Repair Issues – And How We Fix Them

Doors and windows are essential parts of your home or commercial property, but they’re also some of the most frequently used — and abused — components. Over time, even the best installations can develop faults. At Engiglass, we specialise in diagnosing and repairing a wide range of issues with both uPVC and aluminium systems, restoring your fittings to full working order.

Here are some of the most common door and window problems we encounter — and how our experts fix them:

🚪 1. Stiff or Jammed Doors and Windows

Cause: This often results from a build-up of dirt in the track, worn-out rollers, or misaligned frames due to building movement.

Our Fix:We realign the frames if necessary, replace damaged rollers or hinges, and thoroughly clean the tracks. Lubrication is also applied to restore smooth operation.

🔒 2. Locking Mechanism Failures

Cause: Failed multi-point locks, seized handles, or internal gearbox damage are typical in older units.

Our Fix : We source and replace specific locking systems, including discontinued models where possible. All parts are tested post-installation to ensure full security.

🪟 3. Broken or Cracked Glass

Cause: Accidents, thermal stress, or impact damage from outside sources.

Our Fix: We remove and replace broken single or double-glazed units with exact size matches. We also check the surrounding seals and frame for further damage.

🌬️ 4. Draughty Windows and Doors

Cause: Worn-out rubber gaskets or ill-fitting sashes cause unwanted airflow.

Our Fix : We replace perished gaskets and reseal the edges for a tight, energy-efficient fit. In cases of warped frames, adjustment or selective part replacement may be needed.

🛠️ 5. Loose or Faulty Handles and Hinges

Cause: General wear, corrosion, or poor installation.

Our Fix :We tighten, replace, or upgrade handles and hinges, using compatible parts that match your frame type — including concealed hinges or tilt-and-turn mechanisms.

🧰 6. Foggy or Condensed Double Glazing

Cause: A failed sealed unit allows moisture to enter between the panes.

Our Fix : We replace only the affected glass unit, not the entire window or door — saving you time and money.
